Comparison of Biosorption of Cadmium (II) from Aqueous Solution, by Bacillus Sp and Pseudomonas Aeruginosa

Biosorption of Strontium from Aqueous Solution by the New Strain of Bacillus sp. Strain GT-83

An attempt was made to isolate bacterial strains capable of removing strontium biologically. In this study ten different water samples collected from Neydasht spring in the north of Iran and then the bacterial species were isolated from the water samples. The initial screening of a total of 50 bacterial isolates resulted in selection of one strain. The isolated strain showed a maximum adsorptio...

Biosorption of copper(II) and zinc(II) from aqueous solution by Pseudomonas putida CZ1.

To study Pseudomonas putida CZ1, having high tolerance to copper and zinc on the removal of toxic metals from aqueous solutions, the biosorption of Cu(II) and Zn(II) by living and nonliving P. putida CZ1 were studied as functions of reaction time, initial pH of the solution and metal concentration. It was found that the optimum pH for Zn(II) removal by living and nonliving cells was 5.0, while ...

Biosorption of Cd(II) and Ni(II) Ions From Aqueous Solution by Raw and Pre-Treated Cystoseira Indica Algae

Equilibrium, kinetic and thermodynamic studies on biosorption of lead(II) and cadmium(II) from aqueous solution by polypores biomass

Polypores (woody pore fungi) biomass has been used as an biosorbent for the removal of Pb(II) and Cd(II) from aqueous solution under batch equilibrium experimental conditions. The resulting biosorbent is characterized by SEM and FTIR techniques. The effect of experimental parameters, such as solution pH, biomass dosage, contact time, initial metal ion concentration and temperature of Pb(II) and...

Biosorption/desorption of Cadmium(ii) and Zinc (ii) from Aqueous Solution by Activated Sludge Immobilized into Chitosan Beads

In this study, we evaluated the effectiveness of cadmium and zinc adsorption and desorption from solutions containing single metals and a mixture of metals in the ratio of 1:2 by activated sludge immobilized onto chitosan (ASC). The optimal pH value determined for metals adsorption ranged from pH 5 to pH 6, whereas that established for desorption reached pH 2. In the case of individual metals, ...

Comparison of biosorption of cadmium ions from aqueous solutions by the lichens Acarospora strigata, Lecanora muralis and Caloplaca aurantia

Introduction: Biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. Also, living lichens are known to accumulate metals across their surface. Materials and methods: In this study, the biosorption of cadmium ions Cd (II) by the lichens Acarospora strigata, Lecanora muralis and Caloplaca aurantia was investigated in aqueous solution i...
